SANITARY POWER-DRIVEN CARIET BATER.

Application led November 6, 1920. Serial No. 422,345.

To all whom t may concern.'

Be it known that I, Ross C. BEEKMAN, a citizen of the United States, residing at Kansas City, in the county of Wyandotte and State of Kansas, have invented certain new and useful Improvements in Sanitary Power-Driven Carpet Beaters, of which the following is a specification.

My invention relates to a new and useful sanitary, power-driven carpet beater, and one object of the invention is to pron vide a machine of this character which can be operated by power, such as a gasoline engine, electric motor, or the like, thus performing a quicker and more thorough piece of work.

Another object is to provide a carpet beater in which the dust beaten from a carpet or rug may be collected and thus prevent the same from flying about in the air as is now the case when carpets are beaten in the ordinary manner.

The machine, generally speaking, consists of oppositely-disposed rolls over which the carpet is fed forward and backward, said rolls having a beater arrangement therebetween throufrh which the carpet must pass as it moves back and forth over the abovementioned rolls. The machine further consists of means for collecting the dust and discharging it into a suitable container or dust collector, from which it may be blown by a fan into a dust-proof box, sack, or the like.

With the above and other objects in view, reference will now be had to the accompanying drawings, in which:

Figfl is a longitudinal elevation of the carpet beater.

Fig. 2 is a longitudinal section of the machine turned around from the position disclosed on Fig. 1.

Fig. 3 is a top or plan view of the machine.

yFig. 4 is a longitudinal elevation of a fastening device for securing theends of the carpet upon the feed rolls of the machine.

Fig. 5 is a cross section of said fastening device, in position upon the carpet.

Fig. 6 is a cross section of the entire machine.

Fig. 7 is a longitudinal elevation showing the mechanism for rotating the feed rolls and reversing them. l

Fig. 8 is a fra 'entary plan view of the ineens for securing the carpet totherfeed beater bed i:raIne,v being v,or 'other suitable means'. Upon said sarees rolls, and disclosing the manner in which said fastening means reverses the feed rolls.

Referring now more particularly to the machine, the carpet beater, as a whole, is supportedvupon a frame consisting ofcorner posts 2, connected by longitudinal members 4 and cross members 6., Oblique braces 8 are secured to the legs and the cross members 4 and 6, and longitudinal braces 10 are secured to the opposite legs 2. Upright, centralbrace members 1l are secured to opposite sides of the frame, said'braces being connected at their tops by a cross beam l5 which adds strength and rigidity to the frame and serves as a support for a large part of the mechanism.

` In order to feed the carpet backward and forward while being beaten or cleaned, I provide two oppositely-disposed rolls 14, said rolls may be of any suitable construction. The rolls are fixedly mounted upon shafts 22 which` are journaled in suitable bearings, in the frame members 4.

One end of each shaft 22 has a ratchet wheel 24 iiXedly mounted thereon, said wheel having a cooperating pawl 26, mounted on pins 27 secured between small members 29 and depending levers 3l, fora purpose which will hereinafter appear.

The opposite ends of the shafts 22 are provided with ratchet wheels 30 and pawls 32 to prevent their respective rolls from rotating backwardly when the carpet is being pulled forwardly by one of said rolls. Said pawls 32 are pivotally mounted on pins 36 secured in a block 38, a brace 40 l.

being proidded to firmly hold said block in place.

That part of the machine which performs the beating or cleaning koperation consists of two distinct parts, viz a beater bed and a series of beater arms which work in conjunction with said beater bed. Referring to ythe beater bed in detail, the same may be Said to consist of a frame having transverse members 50 and end members 52, said frame being mounted on oppositely disposed pivots 58 journaled in the side members 4 of the frame, so that the entire frame may be swung up when desired in orderl to repair or-remove any obstruction from the dust collector which lies directly under the beater bed, as will hereinafter appear. l coarseA wire Anetting GO is fitted l'over the secured by screws .a belt 92 is secured, over or netting() is mounted a series of springs 61 secured thereto at their lower ends by clips or other means, and at their upper ends by cablesf running` over the tops of said springs and secured thereto in any suitable manner. The ends of said wires or cables are i'irmly secured to the cross members 50 of the beater lbed frame by screws 64 or other suitable means. It will thus be seen that the whole furnishes an open and resilient beater bed through which the dust may sift, as it is beaten vfrom a carpet, down into a dust proof receiver or dust collector, as will hereinafter appear.

Referring to` the beater arms which perorm'the actual beating or cleaning opera tion on the carpet, the same consist of a series of' arms consisting of wire or other suitable material. Said beater arms are secured at their rear ends between an L-beam '72 and a longitudinal lmember 74 firmly secured to said .L-beamby bolts 76 or other means. Both the L-be'am and the member '74 are mounted upon a shaft 80 journaled in the upright frame members 11.

One end ofthe shaft 8O extends outwardly and has a crank 82 :to which is secured a link 84, said link beingl secured at its lower end to a second crank 86. The crank S6 forms partof a shaft 88 extending` across the entire machine and j ournaled in the upright members 11. A pulley 90 'is fixedly mounted on the opposite end of the lshat't 88 to which which power may be transmitted from a. gasoline engine, electric motor, or other suitable source, for operating the machine.

As the Idust vis beaten from a carpet, it

' passes downwardly through the open trame work of `the beater bed into a trough-like dust collector 100, made of any dust-proof ma teriahas cloth, tin, wood, or the like. VSaid dust collector is substantially Ufshape in cross section and is secured at one upper margin to afbeam 102, secured-at its ends to the longitudinal members 4. The opposite margin loi' the dust collector is secured to the back member 50 of the beater bed. It `will thus be seen that the Lipper 'portion of the dust collector is left open in order that dustand dirt Vmay settle therein as it falls `from the beater bed. However, no dust can i escape Yfrom the dust collector as the former is at `all times covered by the carpet A, or

its fastening' means 129.

ln order to blow or discharge the dust from the dust collector, l provide a fan 110 which operates continuously while the machine is in motion. Said fan is journaled in a ydepending` bracket 11 and is provided with a pulley over which a belt 112 operates .to rotatesaid fan. Said fan sucks airin at `the open end of the dust collector, which ter Aas covered 'bv .a screen, .and .thus creates v`a strong 'draft through the dust collector provided, one

which carries the dust to an opening 114 through which it is discharged into any suitable container. lf.' desired the discharge opening' maybe made inithe'side ot' the dust collector and several sections of stove pipe or the vlike `(not shown) connected thereto to discharge the dust out through the end of thc machine vinto a suitable container.

In order to more fully remove all dirt from the carpet, va powerful rotary brush 162 is employed journaledin the side members 4 and having' a basin or .trough-like pan 163 thereunder, into which thelower end ot the brush dips, said trough beinpr lled with a washing iiuid, which is renewed from time to` time by a supply tank at a distance from themachine (not shown) the dirty water being trough as new water is supplied.

A second rotary brush 116 is alsojsupplied being mounted upon a'sh'att 118 journaled in the main frame members 4. Shaft 118 has a pulley 120 which receives power through a belt 122 connected tothe fan shaft 110. y

To allow the extreme ends of the carpet A to move forwardly from their respective rolls, into position over the beater bed, l do not connect said carpet directly to the feed rolls but secure the same thereto through the intermediacy of a holder consisting of ya stoutcloth strip such as Carmes 129, said dischargedv from the any manner, as by screws, etc. end et the strip 129 has a member for engaginc` the end ot' the carpet 11 consisting ot' upper and lower longitudinal vplates 138 and 136 respectively, held together by screws 140, between which the ends of the carpet A can be'iirmly clamped. Two of said fastening;l members are provided, one to secure each end of the carpet to its respective holder. The solid cloth holder 129 also prevents any dust from escaping' vfrom the dust collector should the carpet. run a slight distance beyond the edge oi the beaterbed, which action would leave a portion oi the dust collector open if the carpet were merely secured by ope-n strips.

The main 'iced rolls receive rotary motion through the ratchet wheels`24"brougfh the intermediacy oi" the pawls '26. vSaid pawls in The opposite turn receive their motion trom the lerers''31.

ets and their respective rolls and thus'altery nately pull the carpet back and forth over the beater bed, two push-rods 142 are -provided. beingconnected at their inner ends by a hinge 144. Two pairs of rods 142 are pair beingl on eac'hfsid'e of the.y

main frame.` Saidpush-,rods arev slidably mounted in brackets' 143-,*and are provided with adjustable striking arms 146 and 148, respectively, against which the fastening members 136 and i238 'for holding the carpet are adapted to alternately strike in their travel back and 'forth with said carpet. This action 'forces the push-rods one way or the oth and through the intermcdiacy ot bellcranks 150 and litt rods 162, raises the two ratches on one roll and lowers those on the opposite roll, thereby reversing the motion of said rolls and causing the carpet to travel back and forth.

The operation oi" the machine, briefly stated, is as vfollows: When it is desired to clean a carpet or the like one end ot said carpet is secured in position between one pair of the fastening plates ing it between said plates and tightening the nuts or screws 140, thus drawing said plates firmly together upon the edge ot the carpet, after which the opposite end of the carpet is secured in a like manner to its respective tastening device. The ieed rolls are then turned back tar enough by hand to take up any slack in the carpet, after which the machine is set in motion by applying the power. As the belt 92 rotates its pulley 90 the latter drives the main shaft 8l and the crank 8S on the opposite end oic said shaft 8l. As said crank rotates it movesv its links 86 back and forth which causes the levers 3l to swing back and forth, and through the intermediacy of the pawls 26, impart a step-hy-step rotary motion to the ratchet wheels 24e and their respective shafts and rollers le. As before stated, only one roller lei is kept in motion at a time, the opposite roll merely 'feeding the carpet forward as said. carpet is pulled across the beater bed by the adjacent roller. Backward rotation ot' said roll lll: which happens to be pulling the carpet forward, is prevented by the pawl and ratchet on the opposite end Ol' the roller. rllhe pa'wls and ratchets on the idle roll are held in disengaged position until the carpet has approximately reached the edge of the beater hed, when itsI 'fastening member, which has also traveled forward with the carpet, strikes the striker arm 'l-LtS as shown in Figs. Z and 8, which action through the intermediacy of the puslrrods 142, the bell` cranks 150, and the lift rods '162, raises one set ot pawls out of engagement with its respective roll, and lowers the pawls on the opposite roll, thus reversing the motion ot `the feed rolls and drawing the carpet back and iforth over the heater bed. In the meantime, as the carpet A travels back and forth over the beater bed, the beater arms 4&8 are caused to swing rapidlyT up and down through the intermediacy of their shaft 8O which is given a rapid oscil- Vis the dust is beaten 132 and 138 by securf latory motion through the intermediacy of its crank 82 and the link Se, which latter receives motion from the main power shaft 8l, through the `intermediacy or' the crank 88. trom the carpet it sitts downwardly through the open frame work of the beater hed into the dust collector 100, Afrom which the fan 110 blows it outwardly through the nozzle 114 into a container (not shown).

Having thus described my invention, what l claim and desire to secure by Letters Patent, is: v

l. win a machine of the character described, two rolls around which a. carpet is adapted to be wound, means for rotating said rolls, means for reversing the movement ot said rolls; said reversing means being actuated by the travel ot the carpet, a beater hed over which said carpet travels, beater arms to beat said carpet while a certain. portion ot the latter is over the beater bed.

2.. ln a machine of the character described, two rolls over which a carpet is adapted to travel, means tor securing the carpet to said rolls in such manner as to allow its eXtreme ends to move forwardly a certain distance from the rolls, in order that all of said carpet may be cleaned, means in conjunction with said fastening means for reversing the travel of the carpet when its end has approximately reached the 'edge et the beater bed, and means for cleaning said carpet as it travels over the beater bed.

3. ln a machine of the character described, rolls :tor moving a carpet in alternate directions, means tor applying power t0 one of said rolls for the purpose of rotating the same while its opposite roll is allowed to run idle, means for removing the power actuating means from one roll and applying it to the companion roll, means on the carpet `for controlling said power actuating and reversing means, substantially as described.

e. ln a machine ot the character described,
